Can't connect to skydroid t12

At the first time when I connected my android phone and skydroid t12 transmitter through a usb cable, my phone was able to detect it and I could use the device helper and was able to see the video feed through skydroid FPV.
I haven’t made any changes but now my phone isn’t detecting the skydroid t12 transmitter when I connect it via a usb cable/bluetooth and while using the device helper, it shows connection failed.
Kind request for some assistance.

Hello chinmay i am also facing the same problem? and my skydroid is pairing in bluetooth but it doesn’t connect bluetooth.
Have you found any solution?
